基于SBM模型的重庆碳市场效率评价

Efficiency Evaluation of Chongqing Carbon Market Based on SBM Model

本文通过构建碳市场效率评价指标体系,基于超效率SBM模型从总体和区县两个视角对重庆碳市场效率进行了评价,获得了重庆碳市场及各区县参与碳市场的综合效率、纯技术效率和规模效率。结果显示,总体上重庆碳市场的综合效率和纯技术效率基本能够达到有效,但规模效率能够达到有效的年份较少。重庆各区县在参与重庆碳市场交易过程中还存在很大的效率改进空间,不同区县参与碳市场的综合效率、纯技术效率和规模效率之间存在较大差异,在时间维度上呈现出一定的波动性。最后,针对研究结论提出了重庆碳市场进一步发展的政策建议。

By building the carbon market efficiency evaluation index system and assessing the market's effectiveness using the superefficient SBM model,this paper assesses the Chongqing carbon market′s efficiency from two angles:overall and district and county.It also determines the market's comprehensive efficiency,pure technical efficiency,and scale efficiency as well as each district and county′s participation in the carbon market.The findings indicate that while the scale efficiency can achieve efficiency in fewer years,the overall comprehensive efficiency and pure technical efficiency of the Chongqing carbon market can essentially accomplish efficiency.The process by which Chongqing districts and counties engage in the trading of the Chongqing carbon market still has a great deal of room for efficiency improvement.Additionally,there is a significant variation in the comprehensive,pure technical,and scale efficiency of the various districts and counties involved in the carbon market,indicating some degree of temporal volatility.Finally,policy recommendations for the further development of Chongqing′s carbon market were proposed based on the research findings.
